Purpose: To compare outcomes of type II endoleak embolization involving embolization of the endoleak nidus only vs embolization of the endoleak nidus and branch vessels in patients treated with endovascular repair of abdominal aortic aneurysms.
Purpose: To evaluate the efficacy and clinical outcomes of ancillary endovascular procedures in promoting false-lumen (FL) thrombosis (FLT) and preventing aortic expansion in patients after thoracic endografting for type B dissections.
Purpose: To characterize medical industry–based payments made to US-based interventional radiology (IR) physicians, identify trends in compensation, and compare their payment profile with those of other related specialties, including vascular surgery (VS) and interventional cardiology (IC). Payments made to orthopedic surgery (OS) physicians are reported as a historical control.
Purpose: To determine if patient aspirin exposure and timing affect bleeding risk after renal allograft biopsy.
Objective: For palliation of extrahepatic bile duct obstruction, self-expandable metal stents (SEMS) are superior to plastic stents in terms of stent patency and occurrence of stent dysfunction. We assessed health-related quality of life (HRQoL) after stent placement to investigate whether this also results in a difference in HRQoL between patients treated with a plastic stent or SEMS.
Background/objectives: Nonalcoholic fatty liver disease (NAFLD) is a worldwide public health concern. Coffee might have a protective effect against NAFLD. However, the results of previous reports are conflicting. Therefore, we carried out this meta-analysis to summarize all available data.
Background and aim: To minimize the sample variability of liver biopsy, the tissue length should be at least 25 mm. Consequently, more than one biopsy pass is needed with cutting biopsy needles. We aimed to investigate the risk factors of biopsy-related complication, including the number of biopsy passes.
Objective: Sorafenib is the standard of care for patients with advanced hepatocellular carcinoma (HCC), but data on its use in the elderly are inconclusive.
Background/aim: Contrast-enhanced ultrasonography (US) has improved the detection and characterization of focal hepatic lesions. Recently, the importance of obtaining high-quality samples in the biopsy of hepatic lesions has been increasing not only in the field of pathological diagnosis but also in molecular analysis for predicting the effectiveness of anticancer agents and molecular targeted drugs. We evaluated the utility of Sonazoid-enhanced ultrasonography (SEUS) in guiding percutaneous biopsy of focal hepatic lesions by comparing the results of histopathological diagnosis between B-mode US and SEUS guidance.
Introduction: The assessment of risk factors of cancer recurrence in patients with stage II colon cancer (CC) is crucial. Our aim was to study the clinical, histological, and molecular features associated with 3-year disease-free survival in a series of consecutive patients with stage II CC treated in three regional digestive oncology centers.
Background: Although ultrasonography (US) guided radiofrequency ablation (RFA) is a commonly used treatment option for early hepatocellular carcinoma (HCC), inconspicuous tumors on US limits its feasibility. Thus, we prospectively determined whether real-time US-CT/MR fusion imaging can improve the technical feasibility of RFA compared with B-mode US, and help predict local tumor progression after RFA in patients with HCC.
Background: The primary aim of this study was to compare the rate of global radiofrequency ablation (RFA) failure between monopolar RFA (MonoRFA) vs. no-touch multi-bipolar RFA (NTmbpRFA) for small hepatocellular carcinoma (HCC) ⩽5 cm in cirrhotic patients.
OBJECTIVE. Small pulmonary nodules are often difficult to identify during thoracoscopic resection, and preoperative CT-guided localization performed using either hookwire placement or methylene blue injection can be helpful. The purpose of this study is to compare the localization success and complication rates of these two techniques.
OBJECTIVE. The purpose of this study is to retrospectively evaluate local tumor control, time to tumor progression, and survival rates among patients with lung metastatic colorectal cancer who have undergone ablation therapy performed using laser-induced thermotherapy (LITT), radiofrequency ablation (RFA), or microwave ablation (MWA).
OBJECTIVE. Information is limited on changes over time in the types of fluoroscopically guided interventional procedures performed and associated radiation safety practices used by radiologic technologists.
